I loved Mauricio Fernandez’s new post about rcov. I’m convinced that rcov and unit testing go well together, I’m using rcov to verify my coverage on projects at work, and on projects I work on in my spare time.
Mauricio says that he’s got some new features in line for his 0.4.0 release. Sounds like something worth waiting for — hopefully we don’t have to wait too long.
(Thanks to Sean Carley for pointing it out.)
update
Shortly after I posted this, Zed posted a message to the Rails mailing list letting us know he’s using rcov to look at mongrel’s tests now. You can see his coverage at mongrel.rubyforge.org/coverage/. When I asked him about it, he said “Yeah, [rcov’s] pretty sweet. All that’s needed is a gem and the rake task.”
Alright, 1/2 of that got into 0.4.0, the rest will have to wait a bit (hey, almost 100 changesets are enough for one release :).
RubyGems packages are also on the way --- both a normal one (which requires a C compiler to build rcovrt) and a Win32 binary (for the mswin32 build & recent one-click distros). I've sent a few .gem files around and am awaiting feedback from my vict^H^H^H^Htesters.
